Question
Refer to the soil profile in the figure below. Given Hj= 4m and H2=3m; a) Calculate the total stress, pore water pressure and effective stresses (for points a, b, c and d), and plot the variation in ơ, u and ơ with depth b) If the ground water table rises to 2m below the ground surface, what will be the net change in effective stress at the bottom of the clay layer? c) If a 4m depth of fill material of unit weight 20KN/m³ is placed on the surface over an extensive area. Determine the amount of the effective stress increase at the middle of the clay layer. d) For a 3mx3m square foundation with load capacity of 2700KN is placed at a depth 1m from the ground level. Determine the amount of the effective stress increase at the middle of the clay layer. Dry sand e = 0.6 G, = 2.68 H1 Groundwater table Clay e = 0.8 H, G = 2.75
